Title:Quantum "Pathfinder"

Abstract: It is discussed an opportunity to introduce new class of quantum algorithms
based on possibility to express amplitude of transition between two states of
quantum system as sum of some function along all possible classical paths.
Continuous analogue of the property with integral on all possible paths is well
known due to Feynman approach and ensures the correspondence with classical
minimal action principle. It is less technical and rather popular introduction
to earlier work about application of Lagrangian methods in quantum computing
[quant-ph/0308017].
